| Abstract: | A kind of signal conditoning circuit which applied to the frequency modulation continuous wave(FMCW) radar was proposed.The circuit adopted low noise pre-amplifier,logarithm intermediate-frequency(IF) amplifier and the filter with frequency dynamic compression.Experimental results show that the little signal gain is more than 100 dB and dynamic range is over 80 dB,which has higher signal-to-noise ratio(S/N) and good filter performance.The circuit can effectively improve the anti-jamming ability of FMCW radar. |
| Keywords: | FMCW radar logarithm amplifier anti-jamming dynamic range filter |
